SVGFESpecularLightingElement: kernelUnitLengthX property

Baseline 2024
Newly available

Since ⁨March 2024⁩, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The kernelUnitLengthX read-only property of the SVGFESpecularLightingElement interface reflects the x value of the kernelUnitLength attribute of the given <feSpecularLighting> element.

The kernelUnitLength attribute indicates the intended distance in current filter units, specified by the primitiveUnits attribute, for the x and y coordinates. It contains one or two values, with the y value defaulting to x if not present, and the kernelUnitLengthX property gets and sets the first value.
